AI agents call waypath_health to retrieve information from Waypath without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though waypath_health only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Read-only end-to-end health check: SQLite connectivity and migration version, FTS5 index sync status, source adapter probe results, and truth-kernel row counts. Safe to call any time and from any context. Use as a single diagnostic entrypoint before opening a support issue; for adapter-specific detail call waypath_source_status. Takes no parameters. It is categorised as a Read tool in the Waypath MCP Server, which means it retrieves data without modifying state.
Register the Waypath MCP server in PolicyLayer and add a rule for waypath_health: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Waypath. Nothing to install.
waypath_health is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the waypath_health rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for waypath_health. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
waypath_health is provided by the Waypath MCP server (thestack-ai/waypath). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
